1 ACTIVITY 9: BLOOD AND HEART OBJECTIVES: 1) How to get ready: Read Chapters 21 & 22, McKinley et al., Human Anatomy, 5e. All text references are for this textbook. Read dissection instructions BEFORE YOU COME TO LAB. 2) Histology: Identify elements in a prepared slide or photo of stained human blood. 3) Observe and identify the human heart and other major structures in the thoracic cavity of a human cadaver. 4) Identify structures on models of a human heart. 5) Perform a dissection on a preserved sheep heart or fresh pig heart. YOU MUST BRING GLOVES FOR THIS ACTIVITY. 6) Before next class: Preview Vessels terms lists from SLCC Anatomy Laboratory website or your printed laboratory manual and your textbook. You will be learning many vessels, so preparation is important. TABLE 1.

5 CARDIOVASCULAR SYSTEM: SHEEP HEART OR PIG HEART OBSERVATION AND DISSECTION OBSERVATION: External anatomy of the heart 1. Identify the right and left sides of the heart. Look closely and on one side you will see a diagonal line of blood vessels that divide the heart. The half that includes all of the apex (pointed end) of the heart is the left side. Confirm this by squeezing each half of the heart. The left half will feel much firmer and more muscular than the right side. The left side of the heart is stronger because it has to pump blood to the whole body. The right side only pumps blood to the lungs. 2. Turn the heart so that the right side is on your right, as if it were in your body. Examine the flaps of darker tissue on the top of the heart. These ear-like flaps are called auricles. Find the large opening at the top of the heart next to the right auricle. This is the opening to the superior vena cava, which brings blood from the top half of the body to the right atrium. Stick a probe down this vessel. You should feel it open into the right atrium. Down and to the left of the superior vena cava there is another blood vessel opening. Insert your probe into this; it should also lead into the right atrium. This is the inferior vena cava, which brings blood from the lower tissues. You can also see another blood vessel next to the left auricle. This is a pulmonary vein that brings blood from the lungs into the left atrium. 3. Sticking straight up from the center of the heart is the largest blood vessel you will see. This is the aorta, which takes oxygenated blood from the left ventricle to the rest of the body (the ventricles are the lower chambers of the heart). 4. Behind and to the left of the aorta there is another large vessel. This is the pulmonary trunk (artery), which takes blood from the right ventricle to the lungs. 5
6 DISSECTION: Internal anatomy of the sheep heart. After identifying the external anatomical structures in a sheep heart, perform a dissection of the sheep heart as described. 1. Insert your dissecting scissors or scalpel into the superior vena cava and make an incision down through the wall of the right atrium and ventricle, as shown by the dotted line in the external heart picture. Pull the two sides apart and look for three flaps of membrane. These membranes form the tricuspid valve between the right atrium and the right ventricle. The membranes are connected to flaps of muscle called the papillary muscles by tendons called the chordae tendineae or "heartstrings." This valve allows blood to enter the ventricle from the atrium, but prevents backflow from the ventricle into the atrium. 2. Insert your probe into the pulmonary trunk and see it come through to the right ventricle. Make an incision down through this artery and look inside it for three small membranous pockets. These form the pulmonary semilunar valve, which prevents blood from flowing back into the right ventricle. 3. Insert your dissecting scissors or scalpel into the left auricle at the base of the aorta and make an incision down through the wall of the left atrium and ventricle, as shown by the dotted line in the external heart picture. Locate the mitral valve (bicuspid valve) between the left atrium and ventricle. This will have two flaps of membrane connected to papillary muscles by tendons. 4. Insert a probe into the aorta and observe where it connects to the left ventricle. Make an incision up through the aorta and examine the inside carefully for three small membranous pockets. These form the aortic semilunar valve, which prevents blood from flowing back into the left ventricle. FOLLOWING DISSECTION, DISPOSE OF SCALPEL BLADES IN APPROPRIATE SHARPS CONTAINER AND WASH ALL DISSECTION INSTRUMENTS WITH SOAP AND WATER, THEN DRY THOROUGHLY AND PUT INSTRUMENTS AWAY. DISPOSE OF SHEEP HEARTS ACCORDING TO YOUR INSTRUCTOR S DIRECTIONS. 6
